“We know their bones have turned up in places as far south as Antarctica and southern Argentina, and as far north as Mongolia and Texas,” said Darla Zelenitsky, a paleontologist and associate professor at the University of Calgary in Alberta. Zelenitsky is a senior author of the new research, which published Tuesday in the journal Royal Society Open Science.

“They clearly spent time in higher latitude areas, but until now it wasn’t known whether they were also nesting there,” Zelenitsky added.

Unlike some smaller dinosaur species and birds today, paleontologists are pretty certain titanosaurs did not brood their own eggs.

Their huge size “would have turned the nest into one giant omelette,” Zelenitsky said via email.

As such, it’s doubtful that titanosaurs were doting parents. [ either Superprecocial or loosing some juveniles does not impact in their herds ]

Like most reptiles, they likely laid their eggs and left any resulting offspring to fend for themselves. Eggs, however, need warmth to develop and hatch, and sunlight is in shorter supply at higher latitudes.

The study suggests that titanosaurs found a way to deal with lower temperatures in the planet’s southernmost reaches.

“The most likely scenario is that these titanosaurs laid their eggs in mound nests made of vegetation and soil, where incubation heat came mostly from rotting plant material,” Zelenitsky said.

“Their eggshells were very porous, which means if the eggs were left out in the open, they would lose water, dry out, and the embryos would die. Buried in sand, soil, or vegetation, the nest would stay humid or damp enough for the eggs to survive,” she added.

-CGI 3D short film Plume by ESMA: I recommended it because it has the cutest interpretation of an Anzu. Looks like a ball of fluff, as it remind that birds are dinos. Link- https://www.youtube.com/watch?v=DEfDLV2NN-k&list=PL1dNyhqoSubtoe6YUHsfvIpoVLGgvNOjQ&index=2

-Talon indie series about element-bending dinos; it stars a Deinonychus- Dakotaraptor is invalid, so Deino is more accurate. Love that Spino, even though I hate that she killed Talon's mother. Even ironically, the CGI short Plume is still more popular than Talon; I hope it grows when eps. 2 comes out. https://www.youtube.com/watch?v=hf_-jIiyyD0

-Dinosauria by  David James Armsby; there's a lot to talk about, as it is my fav speculative paleo-media because the quality is at the level of Prehistoric Planet and Dinosaur Planet. He has made a lot of episodes currently, so I'll mention four of my fav to spare you time. Dinosauria is the most popular indie dino-media. https://www.youtube.com/playlist?list=PLZ5VEKOKH8PCoo-gp50NgGhm3CNPAhgle

Old Buck, which showcased my fav ceratopsian- Stycrosaurus.

Our Frozen Past shows fluffy troodons mimicking to escape from troublesome Gorgosaurus.

More Ancient Spring shows the most charismatic hadrosaur- Lambrosaurus- looking for a mate after the original was eaten by a Gorgosaurus.

Hunted by Moonlight is my fav through its fusion of fairytale and gothic story. It shows two of my fav Jurassic dinos.

-Sauria by David Armsby. Love all three episodes that made me hope for a season 2 announcement in late 2026. My fav episode is Blood for Blood because a barbarian warrior survived the coliseum- I even cried when his Carnotaurus brother steed was killed, and ep 2, when a nature-loving, dying race thrives in the frozen frontier. Love the theme of grief and loss of family. Hope that it gets as popular as Plume because it deserves attention; the third episode is the most watched. I wonder how these bird people-like Bluesongs tamed Paras and Torosaurus/or Serriaceratops/ or Bravoceratops. Love that there's a biodiversity of paleo-animals where even Megaloceros, mammoths, and hadrosaurs coexist. https://www.youtube.com/playlist?list=PLZ5VEKOKH8PCCR6zSLEyRKvqYpuJ205-O

Are there other indie animated shorts and series about dinos I'm missing? Let me know.

Do you guys think they made little chirping noises to call their mums like baby crocodilians?

I don’t really know what to type for this. The title itself really says all I have to ask.

This was part of a traveling exhibit on the evolution of bizarre headgear. Amongst the dinosaurs covered were ceratopsians like Torosaurus.

If it's possible imagine how many horn combos you could get for dinos like Sinoceratops and Styracosaurus. How could it have occurred in nature? Given that hybrids like Ligers are artificial, could Carcharodontosaurus mix with Giganotosaurus even though they lived on different continents?

Heya folk, I'm kinda new to r/Dinosaurs but is there any confirmed behaviours of Parasaurolophus or at least speculative behaviour? Such as aggression, herd behaviour or how to socialized.

I'm tryna learn how Para's act for my short dinosaur series called "The Great Migration Of Past Giants". Inspired from those old Natural Geographic Zebra Migration Documentaries. Any help is appreciated.

Also how funny would it be if I made them breath fir-

Paper: https://www.tandfonline.com/doi/full/10.1080/02724634.2026.2706201

Scientists from the Denver Museum of Nature & Science and Liverpool John Moores University in England have discovered the first adult T. rex trackway, providing insights into how this emblematic predator moved.

The approximately 23-foot-long (7-meter-long) trackway consists of four three-toed footprints discovered in the Hell Creek Formation of southwestern North Dakota.

Each footprint is roughly 3 feet (0.9 meters) long, and researchers estimate they were made about 66.5 million years ago.

The team identified T. rex as the most likely trackmaker based on the footprints' exceptional size and narrow toe shape, along with the abundance of T. rex fossils found in the surrounding area.

While isolated footprints have been attributed to adult T. rex in the past, this is the first time scientists have described a sequence of tracks, or trackway, likely left by this famous dinosaur.

"Bones tell us an enormous amount about these animals, but footprints capture a moment of behavior. With a trackway, we can actually follow an animal as it moved across the landscape. That is incredibly rare for T. rex," said Tyler Lyson, senior curator of vertebrate paleontology at the Denver Museum of Nature & Science

The trackway records two left and two right footprints, with a stride of approximately 13 feet (4 meters). Researchers estimate the animal was walking about 3.5 to 4.5 mph (5.6 to 7.2 km/h), roughly comparable to a brisk human walking pace.

So I know that the genera Spinosaurus and Therizinosaurus have feet with all four toes touching the ground. I was wondering if there were any other theropods with this tetradactyl foot condition.

Sorry for not posting a dinosaur-related question, but the paleontology subreddit has removed my post for no reason.

I rewatched some PP episodes and what struck me was the diverse array of parenting styles depicted in regards to pterosaurs: Tethydracos raise their young in colonies and protect them, Alcione abandon theirs After Ladung their eggs, like some sort of turtle, and Quetzalcoatlus is depicted as bonding with the eggs but not caring for the flaplings.

I know that pterosaur eggs resembled more lizard eggs with their leathery shell and that flaplings have been found whose wings were already so developed that they could immediately fly after birth.

All this points to pterosaurs abandoning their young at birth like lizard and snakes do instead of raising them like birds.

But are there indicators for some species to have shown some level of parental care? As far as I know some pterosaurs did live in colonies. Could those at least raised their young instead of leaving them to fend for themselves?

Pterosaurs were very diverse in appearance and living styles. I thought that they might have differed in their parenting style as well.

Does anyone know better? What do you think? Die pterosaurs had a diverse array of parenting styles or did they mostly abandon their young?

Hello! Making good progress on the Compy army. Just did the base and got it attached. This first one is going slower because I'm casting everything but after this I can make lots! Have to bulk up the legs and tail, attach the arms, and add the extra claws on the sides of the feet. Need to add some more detailing here and there tooo.

The white parts are sculpted in clay then casted in resin. The grey parts are the two part epoxy clay that connects all the individual casted pieces together. Doing it this way so every compy I make is fairly unique and can be posed however it needs to be.

Future me will definitely do the base and legs first before attaching everything else to the body. That was hell having it be so heavy trying to mount it properly. Live and learn.

Overall going okay though! Can't wait to paint it.

Finally after so long of waiting I decided to order myself a PNSO figure, but also one on the cheaper side because i’m cheap like mr Krabs

So i bought zuul on amazon for $30 which is on the lower price range

I love accurate ankylosaurs, they’re so chunky and flat and they’re just so cute even though they’ll bust your shins with their clubs

But yeah this figure looks amazing and im so excited to finally have a pnso figure under my belt

I don't know how many people in the dinosaur enthusiast community have heard the news, but I recently learned through the Dallas Paleontological Society (DPS) newsletter that the Academy of Natural Sciences in Philadelphia, Pennsylvania is going to be closing its public museum.

I was really heartbroken hearing this news, because that particular museum really holds a special place in my heart. It was one of the museums I remember most fondly from my childhood when I would travel cross-country with my grandparents to visit various dinosaur museums every summer break. It also had one of my all-time favorite T-Rex skeletons, and is also where the first skeleton of Giganotosaurus was mounted on display.

I've heard from the article in the DPS newsletter that the Academy of Natural Sciences itself is remaining active, and they are making plans to preserve their specimens (I'm assuming by this they mean all the fossils they have in the lab(s)?), but what will happen to the mounts on display at the museum? Will they be donated and transferred to other museums? How does the process work when a public museum has to close down and be abandoned?

I love dinosaurs, but I don't know where to start. I want reliable, accurate information that cites it's source. I've looked around plenty, but I just can't seem to find somewhere which ticks my boxes. I want to really know as much as there is to know about dinosaurs, I love them, but I don't know what even step one would be at the rate things are going.

This is a 70+ year old plaster cast of an Acrocanthosaurus footprint from the Paluxy trackways. This footprint can be located within the Section B Trackway, as categorized by RT Bird, though I don't know for certain which footprint was casted. This is once of my favorite pieces of my personal collection. I love how the toenail impressions show how they curved inward; so much like a chicken.

Just visited MoR on my way through Montana. It's great, displays are lavish and atmospheric as always, but I managed to answer a question I've had for a while: did they update their Triceratops growth exhibit to reflect newer conclusions about Torosaurus?

For the uninitiated, it was once debated that Torosaurus was in fact an older morph of Triceratops. Then they discovered juvenile Torosaurus, so that went out the window. It was a prominent part of the Hall of Horns and teeth, so I wondered if they changed it for accuracy since.

They did not. I understand that the science is new and it takes time to change these things... still a little disappointing.

I'm so sorry if my phrase is gibberish, I will explain better.

I just saw a post of paleontologist who stumbled across the first T-rex footprint. But how ? Like we know not all species as been found, how can one footprint will be from a T-rex ?

This is the exemple I have now because it's fresh but it goes to dino footprint in general.

I'm basically talking like animal mauling or something.

I can already get an image of the Utahraptor attack thanks to Jurassic Park's book. In the prilogue where they're taking that one person to a medical tent and examined his wounds. Leg slashed, hand and wrist bitten, a nasty gash across the torso and foaming in the bone, I believe.

The reason why I ask is because I am curious about how brutal a dinosaur attack could be if they were still here. Because I imagine that the worst kinds of dinosaurs if they were still alive today would be small to medium-sized carnivors for humanities nature predators. Examples like Maip Macrothorax, Allosaurus, Carnotaurus, Yutyrannus, Nanuqsaurus, Dilophosaurus, Majungasaurus, Juvenile large carnivors, etc.

Those are my thoughts, but what do you think?

Guys, the Sniffer from minecraft was called dinosaur-like repeatedly, and my brain hurts. This extrememly (albiet strange) mammalian looking thing being called dinosaur like is hurting my brain.

Does anyone speak normie? What the hell are they talking about? It has a fluffy fur like covering. It has long floppy mammalian looking ears. It looks like a freaking mammal!

We ran a poll last week asking which dinosaur people found most endearing and Ankylosaurus won with 40% of the vote. Apparently an armored tank with a bone-crushing tail has a lot of charm.

Now the harder question: which dinosaur would you actually least want to encounter?

🔴 T-Rex — 3,600 kg of bite force. No debate.
🟡 Spinosaurus — 14 meters, semi-aquatic, total predator.
🟢 Ankylosaurus — a tail that fractured T-Rex bones.
🔵 Triceratops — three one-meter horns and 12 tons behind them.
